An additional two individuals are now in custody related to a robbery at London's Heathrow Airport where 21 people were injured by a substance believed to be pepper spray, as stated by police.
A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions come after a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the incident, two women were robbed of their luggage after getting out of a car park lift.
A toddler aged three was among the injured in the event. A total of five individuals were taken to the hospital for medical care and were later released.
Officers arrested a man in his thirties on suspicion of robbery and assault close to the scene. He has since been released under investigation while inquiries continue.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding a number of people injured by an irritating chemical believed to be an irritant spray.
The assault - which police said was a standalone incident and not considered terrorism - caused train delays and the partial closure of the main airport tunnel and the T3 parking facility briefly.
